| Abstract: | An air-cleaved mica surface does not yield any low energy electron diffraction (LEED) pattern. A surface cleaved in argon shows LEED patterns with beam energies of more than 70V. The patterns show unusual spot-splitting with different orientations an separations. The vacuum-cleaved surface produces diffuse spots with streaks which degenerate into triplets or triangles on prolonged heating of the sample. All patterns disappear after two or three days. Complex electrical fields at the mica surface have been found to be responsible for the unusual LEED patterns . |
